Wifi PCi adapter is giving me a VBox Host only error? Not sure why

I have a dual boot system. I have recently purchased a wifi pci card because I have been using an old USB Cisco Valet which never worked with windows 10 and is about 10 years old, so it was time to upgrade.

Here is the error:
"Virtual-box host only network doesn't have a valid ip configuration"

Windows 10 - runs well, found the driver and the internet work
Window 7 - VirtualBox Host only network doesn't have a valid IP address configuration.

I have tried several methods to fix this, but nothing seems to work.

I have been searching for an answer, microsoft says to delete virtual box :
"Wi-Fi" doesn't have a valid IP configuration - Microsoft Community

I suppose I could try to use cisco valet for windows 7 only, but it defeats the purpose. Any suggestions?

I'm confused. You say this is a dual boot setup, but it looks like it's not a dual boot setup but you are using a virtual appliance. If this is in fact the case, I think it's due to Virtual Box's poor emulation. If you want to virtualize an OS, I highly recommend VMware Workstation Player.

The other issue could be that the guest OS, Windows 7 in this case needs to be configured as a bridge. If it's in bridging mode try NAT in Virtual Box.

You are speaking over my head, but I do appreciate the help!

I'm using a free dual boot program, is that why you are saying it's virtual? It is easybcd, is that what you are referring to? Is that causing problems? Is there a better way?

Ty. So am I ok to uninstall the Oracle VM VirtualBox ? It is not needed anymore?

Any idea why it is installed in the first place? I don't remember installing it...

No I'm the only one. I just wish I knew what it was used for, which programs need it or access it. I will uninstall it once 8 have a bit more information on its purpose.
